i have shot them with my win 270 using a 130gr ballistic tip and also a 308 165 gr ballistic tip both animals were kill around 300 yards with one shot to the boiler room. Yes it does leave a nice hole on both sides especially the exit. like 3" holes but if you shoot them right behind the shoulder not on the shoulder then really you will not loose valuable meat. or you can just shoot them in the neck. no real meat lost and they will drop right where you hit them. patients is the key goats are somewhat curious animals and unless they really see you they won't just bolt and start running however they will gather their does up and leave rather quickly if they feel threaten. usually they will give you a side shot if you play your cards right.

You should be just fine with your set up. I (2nd from left) harvested the fawn antelope below during a damage hunt in 2003 with 180 BT in .300WM ~ 150 yards with very little meat damage - ~ 2" exit wound.

I have shot several antelope with your exactly BT set-up. It works very well. Again, try to stay off the shoulder but quite frankly, there isn't a ton of meat on an antelope front shoulder anyway. On antelope, I wouldn't expect much difference in meat damage between the Nosler and the Berger, I've shot them with both in 7mm.
